Common garbage bag materials are polyethylene (PE), polyvinyl chloride (PVC), polypropylene (PP), etc. The characteristics of different materials of garbage bags are different, and the application scenarios are also different, the following is a specific introduction:
PE garbage bag
High density polyethylene (HDPE) garbage bags: HDPE material is tough and durable, not easy to break, with good water resistance and corrosion resistance. Due to its high strength, it is suitable for loading heavier garbage, such as construction waste and metal waste in households. In industrial scenarios, it can also be used to collect heavier waste such as some parts and components trimmings.
Low Density Polyethylene (LDPE) Garbage Bags: LDPE has a soft, flexible texture and better transparency. This type of garbage bag is commonly used in daily household life, such as kitchen garbage and general garbage collection in the living room. Its softness makes it easy to put on the garbage can and not easy to break. In some small commercial places, such as convenience stores, small restaurants, etc., LDPE garbage bags are also used to collect daily garbage.
PVC garbage bags: PVC garbage bags are more flexible and glossy, and are usually thicker than PE garbage bags. It is relatively low cost and suitable for mass production. However, its environmental performance is relatively poor, and it is not suitable for some scenarios with high environmental requirements. Generally, it can be used in some places that do not require high performance of garbage bags and focus on cost, such as construction sites and temporary garbage dumps.
PP garbage bag: PP garbage bag has high heat and chemical resistance and better strength. It can withstand certain high temperatures, so it is more suitable in some scenarios where hot garbage needs to be disposed of, such as cafeterias, restaurants and other places where hot leftovers are generated in the kitchen. In addition, PP garbage bags are also suitable for some of the chemical substances have protection requirements of the scene, such as laboratories, chemical plants and other collection of waste containing chemical reagents, but need to be based on the nature of the specific chemical substances to choose the appropriate PP garbage bags.
Biodegradable garbage bags: Biodegradable garbage bags are usually made of biodegradable materials, such as polylactic acid (PLA), starch-based materials and so on. This kind of garbage bag can be decomposed in the natural environment within a certain period of time, reducing the pollution to the environment. It is suitable for places with high environmental protection requirements, such as schools, parks, scenic spots and other densely populated places with high environmental aesthetics requirements, and also suitable for some families who advocate green living.
Drawstring garbage bag: This kind of garbage bag has a drawstring, which is convenient to tie and carry, and can effectively prevent garbage from scattering and odor emission. Whether it is for daily use at home, or in offices, hotels and other places, drawstring garbage bags are widely used for their convenience. Especially in some places that need to clean up garbage frequently and have high hygiene requirements, drawstring garbage bags can reduce the contact between garbage and the outside world and keep the environment clean.
Classified garbage bags: With the implementation of the policy of garbage classification, classified garbage bags have come into being. They usually have different colors and logos for distinguishing different types of garbage, such as blue for recyclables, green for food waste, red for hazardous waste, grey for other garbage and so on. These bags are mainly used in communities, schools, institutions and other places where waste separation is practiced, making it convenient for residents and staff to separate garbage and put it away, and improving the recycling rate of garbage.
